I was doing a search for the Sony PS3 and stumbled upon your system page. My intention is similiar to Mitch4t. I was curious if the PS3's performance in blu-ray can compete with standalone blu-ray players up to $1,000.
Since you have asked, I would suggest that your next upgrade would be a flat-screen 50" plasma or LCD. Your impressive B&W speakers have outshone your CRT box.
Cheers.
